C&K 7403P3YZGI Toggle Switch 4PDT Equivalent & Substitute Parts

Part Overview

The C&K 7403P3YZGI is a panel-mount toggle switch with 4PDT (four-pole double-throw) configuration rated for 5A at 120V AC and 28V DC. This switch features an On-Off-On function with a flat anti-rotation actuator and solder lug termination. The product is active and ROHS3 compliant with an electrical life rating of 40,000 cycles. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical mounting specifications, and functional circuit configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7403P3YZGI are identified based on strict equivalence of the following critical parameters:

• Circuit Configuration: 4PDT topology required for functional compatibility
• Switch Function: On-Off-On operation maintained across all substitutes
• Electrical Ratings: 5A current capacity and 120V AC / 28V DC voltage ratings must be matched
• Mounting Specifications: Panel mount with 6.35mm circular cutout and 1/4-40 bushing thread
• Termination: Solder lug connection style
• Operating Temperature: -30°C ~ 85°C range
• Electrical Life: 40,000 cycles minimum

The E-Switch 1004P3T1B1M1QE and 1004P3T1B1M1QEH meet all these criteria and are direct functional equivalents. Differences in actuator type (flat anti-rotation versus standard round) and actuator length (11.43mm versus 10.41mm) do not affect electrical or mechanical compatibility within the specified panel cutout and bushing thread dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both E-Switch substitute parts (1004P3T1B1M1QE and 1004P3T1B1M1QEH) are functionally equivalent to the C&K 7403P3YZGI based on matching electrical specifications, mechanical mounting compatibility, and regulatory compliance. All three parts are ROHS3 compliant with identical ECCN and HTSUS classifications.

The 1004P3T1B1M1QEH variant offers higher inventory availability (1991 pieces) compared to the 1004P3T1B1M1QE (764 pieces), which may be a consideration for supply chain planning. The C&K 7403P3YZGI maintains 944 pieces in stock.

Selection between these parts should be based on procurement lead times, inventory requirements, and established supplier relationships, as all three meet the specified electrical and mechanical requirements for 4PDT toggle switch applications at 5A / 120V AC operation.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 1004P3T1B1M1QE be used as a direct replacement for the C&K 7403P3YZGI?

A: Yes. Both parts share identical electrical ratings (5A, 120V AC, 28V DC), circuit configuration (4PDT), switch function (On-Off-On), and mechanical mounting specifications (panel mount, 6.35mm cutout, 1/4-40 bushing thread). The solder lug termination and operating temperature range are also matched.

Q: What is the difference between the two E-Switch substitute parts?

A: The 1004P3T1B1M1QE and 1004P3T1B1M1QEH are electrically and mechanically identical. Both are from the E-Switch 100 series and meet all substitution criteria. The primary difference is inventory availability, with the QEH variant offering higher stock levels.

Q: Are there differences in actuator design between the C&K and E-Switch parts?

A: Yes. The C&K 7403P3YZGI features a flat anti-rotation actuator (11.43mm length), while the E-Switch parts use a standard round actuator (10.41mm length). These design differences do not affect electrical compatibility or mechanical fit within the specified panel cutout and bushing thread dimensions.

Q: Do all three parts meet the same regulatory compliance standards?

A: Yes. The C&K 7403P3YZGI and both E-Switch substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. All three share the same ECCN (EAR99) and HTSUS code (8536.50.9065) classifications.

Q: What electrical life rating should be expected from the substitute parts?

A: All three parts are rated for 40,000 electrical cycles, providing equivalent operational durability for On-Off-On toggle switch applications.
